Service bulletin M2021-011

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Beginning with the model year 2021, YZ and WR motorcycles will no longer be provided with an Owner’s Service Manual in the crate. These models will be provided with an Owner’s Manual only. The Owner’s Service Manual can be found on the Knowledge Center on YDS or for customer download on the consumer website at https://www.yamahamotorsports.com/yamaha-manuals. To purchase a printed manual, please visit https://www.yamahapubs.com for more information.

The document

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.
